APPARATUS FOR HACKLING ANDJVDRAWING.

' SPECIFICATION forming part of Letters Patent No. 654,64 dated July e1, 1900.

' Application filed mum is; 1899. semi No. 702,566." on modeln To all whom it may concern:

Be it known that I,"EMIL KoRNIatUnER,

manufacturer, of Libau, in the Empire of Russia, have invented certain new and useful Improvements in Apparatus for Hackling',f Oarding, and Drawing, of which the follow-' ing is a specification.

The present invention relates to an apparatus for hackling and drawing which has the purpose of taking off the fibers entirely and unhurt from between the teeth of the cylinder and conveying them to the next drum or to the winding-on frame or to the coiler. The

new apparatus thus replaces the entire complicated doffing apparatus used hitherto.

In the accompanying drawings the in ven-Q tron is represented, for instance, as applied.

to a hackling and drawing frame.

Figure l is a longitudinal section, and Fig. 2 a plan view, of the apparatus. Fig. 3 is a plan view of a portion? of the net enlarged from that of Fig. 2. Fig. t shows a diagrammatic View of a modification. tional view showing the parts of Fig. 1 supported on the framework and certain means of adjustment.

Essentially the apparatus consists in an endless net made of parallel bars cl, which are interwoven with diagonal wires or cords e e. The net runs over the drum a and a guide-rollerfi The needles of the drum are arranged in parallel rows in such a waythat after a certain number of rows a greater space between the rows is provided, so that a bar 01 of the net can enter in this space. The distance between these spaces is the same as the distance between two bars of the net, so that the bars enter always into'these spaces In order that the motion of the drum may always correspond to that of the net, on both sides of the drum a and the roller f chain-wheels b and f are provided for chains 9, to which the bars 61 of the net are fastened. Prefer ably the ends of the bars form the bolts for the chains g, as shown in Fig. 3. As the net lies directly on thecircumference of the drum, the needles projecting over it take olf the fibers and lay them on the net, which on its" part takes them from the needles when it leaves the drum. Qn the net the material is conveyed to the next drum or to the windingon frame or to the coiler. In order that the Fig. 5 is a sec "greater than that of thenet.

material maybe securely brought between the teeth of the next drum, especially when it is somewhat rigid, a pressing-rollerl is provided.' The free length of the net corresponds to the length of the material.

,If the'same machine is to be used for ma- .work carrying one set of rollers adjustable toward and from the, adjacent section of the framework by means of a pawl and rackm y. 1 The cylinder 71. is adj ustable vertically in slots z of the framework. This device, however, does not allow great differences in the lengths of the material. For greater difierences another device must be employed. Under the working part of the net one or more supporting-rollers 7; are arranged, and above them corresponding movable pressing-rollers 7c, the net, with the material lying on it, passing between them; i The distance between the pairs of rollers must of course correspond to the length of material, because if stretching shall take place the fiber ends must still be under the one pair of cylinders, while the heads have entered between the nextpair of cylinders. By these means the material is uniformly transported and at the same time the not itself is guided. The device just now described may also be used for the purpose of drawing the material. To'this end the speed of the pressing-roller 70 must be WVhen several pairs of rollers are employed, the speed of the following roller must be greater than that-of the preceding one in order to obtain a successive drawing, as shown in Fig. 5. The difierence ofspeed of the rollers is accomplished by means'of bands and pulleys t" 7t i" k.

In short, the advantages obtained by the 7 new apparatus are the following: liIaterial of every length can be worked when the last-described devices are employed. Thelf lre cannot be torn, as they are not at allheld The guide-roller f and fast during the whole process. 'lherefrom results a very light-working condition and a faster working of the machines, the fleeceor band being nevertheless of the utmost uniformity. Because of the latter fact the drawing process can be considerably shortened.

'At least it is to be mentioned that the fire danger is considerably diminished by thenew apparatus. I

What I claim as my invention, .anddesire to secure by Letters'Patent, is-

1. In combination, the drum having the needles disposed in rows withspaces between, an endless net running over the said drum" and having bars (1 tofit inthe spaces between the needles, means for keeping the net with the barsin proper position relatively to the drum, said means .consisting of the sprocketwheels onopposite sides of the drum and chains attached to each side of the net and a guide-roller adjacent to the drum over which the net runs, substantially as described.

2'. In combination, the drum having the needles disposed in rows with spaces between .an. endless net running over the said drum and having bars (1 to fit in the spaces between the needles, means for keeping the net with the bars in proper position relatively to the drum, said means consisting of the sprocket-' wheels on opposite sides of the drum and chains attached to each side of the net and a guide-roller adjacent to the drum over which the net runs, and a gravity-roller'h engaging the lower part of the net, substantially as described.
